Reading here:
https://github.com/cemerick/friend
I see this:
(Note that Friend itself requires some core Ring middlewares: params,
keyword-params and nested-params.
I did not have nested-params so I will add this.
This might be a stupid question, but why doesn't Friend include the
Ring middlewares that it depends on? Why do I have to manually hook
these in when writing my app?
